Trichloroethane Detection Tubes 2/a (2 - 250 ppm)
For short-term measurements more than 160 Draeger Tubes are available to measure the so called spot concentrations of specific gases.
A wide range of different gases and vapors can be detected and measured, such as:
- Determining and measuring concentration peaks
- Measuring personal exposure in the inhalation area
- Detecting leaks in pipelines, gas installations etc.
- Air analysis in sewers, shafts and confined spaces
|Standard Measuring Range:
||20 to 250 ppm / 2 to 50 ppm
|Number of strokes n:
||3 / 5
|Time for Measurement:
||approx. 1.5 min / 2.5 min
||± 10 to 15 %
||pale gray ──> orange
||10 to 40 °C
||5 to 15 mg H2O / L
||Cl2 + o-tolidine ──> orange reaction product
||Other chlorinated hydrocarbons are indicated, but with different sensitivities.
Free halogens and hydrogen halides in the TLV range are also indicated. It is impossible to measure trichloroethylene in the presence of these substances. Petroleum hydrocarbons cause low readings.
